Philadelphia Eagles coach Andy Reid, who is on the hot seat himself, is making a change in his staff that he hopes will help get his 3-3 team back on track toward the playoffs. The team fired defensive coordinator Juan Castillo on Tuesday, replacing him with defensive backs coach Todd Bowles.

Under Castillo this season, the Eagles have struggled to get their trademark edge pass rush going and have gone three consecutive games without a sack—the first time since 1983 that has happened.

That contributed to consecutive losses to the Pittsburgh Steelers and Detroit Lions, in which quarterbacks Ben Roethlisberger and Matthew Stafford engineered successful fourth-quarter comebacks.

The Lions game was especially troubling, as without pressure up front, the Eagles' talented secondary got burned several times as the Eagles yielded 20 points in the fourth quarter and overtime.

"We’re six games into the season and average isn’t good enough," Reid said in announcing the move. "I know the potential of our team and insist on maximizing it.”

Castillo served as the Eagles' offensive line coach from 1998-2010. Reid's move to make him coordinator on the other side of the ball was met with initial questions, and Castillo wasn't able to answer them in 22 games.

Bowles will have a bye week to figure out how he wants to better scheme the Eagles' defense.
